SPECIFIQATION forming part of Letters Patent No. 334,986, dated January 26, 1886.

Application filed October 13, 1884. Serial No. 145,379. (No model.)

T0 to whom it may concern.-

Be it known that I, SAMUEL F. SEELY, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented new and useful Improvements in Folding Canvas Cots and Stretchers, of which the following is a specification.

My invention relates to improvements in canvas cots and stretchcrs, and the objects of my improvements are, first, to constructa cot that can be easily and compactly folded; second, to construct a cot cheap and simple in its construction; third, to obtain asimple,easilyadjusted, self-sustaining head rest or back and shoulder support; fourth, to construct a folding cot that is easily convertible into a stretcher for camp, hospital, or police use; fifth, to combine in a hinge for a cot all the necessary features of folding, sustaining, and locking the same in position for use. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of the cot in position for use. Fig. 2 is a perspective end view showing the self-sustaining head-rest. Fig. 3 is a front View of hinge H enlarged.

' Fig. 4 is an enlarged view of the right side of the hinge H. Fig. 5 is an enlarged view of the left side of the hinge H complete. Fig. 6 is a bottom view of the hinge H complete and enlarged, and Fig. 7 is an enlarged view of the back of the hinge H.

In all of these views like letters refer to like parts.

A A are combination-rails, consisting of two parts, a a, to which a canvas covering, 0, is attached by tacks or other suitable means.

B is an elevation for a head-rest, formed by the double-curved arms 7) b, pivoted near the lower edges of the rails A A.

D D are sets of legs pivoted together and pivoted also at their upper ends to hinges H H, secured to the rails A A.

E E are brace-rods pivoted to one leg and engaged over the other by means of the hooks e e, which securely stay the legs in extended position and allow them to be folded or turned up between the rails A A, where they are secured by means of the chains U U and pins V V, thus converting the cot into a stretcher;

The torsional strain of the curved arms I) b on the rails A A,caused by the pressure on the canvas at the pointB, makes a self-sustaining head-rest that may be placed at any desired height, it being necessary for the hinge H to be attached to the rail A at a point outside of and a few inches away from the point of attachment of the double curved arm b.

One or more tension-blocks, T, may be inserted between the combination-rails A, consisting of parts a a, at any point desired where the greatest amount of strain may be given on the canvas 0.

In a cheaper class of cots I design to dispense with the tension-blocks T, 8m, and .make the rail A single, the double-curved arm I) being attached in the same manner.

In the hinge H, I is a back plate arranged to go against the inside of the rail A and be secured to the same by means of bolts, screws, or rivets. The stud S is driven into the wood and the arm L is bent closely around the rail A and secured by means of a screw at the end.

J is a plate pivoted to the back plate, I, by means of the bolt, screw, or rivet M.

J J are two wings extending out from the plate J, between which the upper end of the leg D is fitted, and to which it is pivoted by means of the bolt or rivet K.

j is a brace to support the wing J by its bearing on the plate I.

P and l? are studs or stops on the plate I, between which the plate J moves to allow the legs to fold up.

N is a pawl or button that engages in a notch, n, to retain the legs in position when the cot is extended in position for use.

The hinges H H, &c., are rights and lefts, and one is attached to the upper end of each leg D and to the rail A.

Having thus described the parts of my cot and the manner of working, the combined operation of the cot is plainly understood and easily performed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a canvas cot and stretcher, the combination, with the side rails, of cross-legs united thereto by hinges H, each having a back plate,

ICO

I, a stud, S, and an arm, L, adapted to partly embrace the side rail upon itslower edge, substantially as specified' 2. In a combined canvas cot and stretcher, hinges H H, 810., consisting of the following parts: a plate,I,having a stud,S, angular arm L, and stops P P, fitted and secured to the rail A by means of bolts, screws, or rivets, to which is pivoted a plate, J, having two projecting Wings,

J J and bracej, and catch n,adapted to engage With the pawl N, to the wings J J of which is pivoted also theleg D, forming a double-j ointed hinge, as described and specified.
